IMPROVEMENT IN MOULDING-MACHINES.

The Schedule referred to in thesevLetters Patent and making part of thesame. y

To all whom it mol/y concern:

Be it known that I, ISAAC P. TICE, of New York, in the county of NewYork, and State of New York, have invented a new Improvement'inWood-Moulding Machines and I do hereby` declare the following, whentaken in connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in

Figurel l, a side view; j

. Figure 2, a side view of the cutter, and a portion of the arbordetached Ilgures.Stand 4, vertical central sections` through the arbor,at right angles to each other; and in Figure 5, a face view of themoulding cut upon the inclined table. A l

This invention' relates to an improvement in woodmoulding machines,particularly applicable to the machine patented to Nathaniel Gear,November 8,1853, and extended in 1867, the object being to improve theadjustment of the cutters and increase the facilities of the machine;and l v g The invention consists 'in constructing the collar between thetwo sets of cutters intwo parts, the one screwed on to the other,so'that the upper cutters may overlap to any desirable extent on to thelower cutters, and the elevation of the upper cutters be changed withoutnecessarilychanging thelower cutters.

To enable others to construct and use my improvement, I will fullydescribe the same as illustrated in the accompanying drawings.

A is the frame;

' B, the table; and

C, the arbor or shaft, all constructed and arranged in the usual manner.

, Upon the shaft is xed or formed a lower head, D, to receive the loweredge of the lower cutters d, usually two in number.

' a-a are the upper cutters, also usually two in number.

Heretofore, between the two sets of cutters has been arranged a collar,ina single piece,'iit'ted upon its under side to receive the upper edgeof the lower cutters, and upon its upper surface, in like manner tted toreceive the lower edge of the upper cutters, a second head, E, beingplaced on to the shaft,so'as to support the upper edge oftheuppercutters, and coniined, so as to hold all the cutters in place.

By this arrangement, it will be seen that the collar between the twocutters, being in one piece, renders impossible the adjustment of theupper and lower cutters relatively to each other, a serious d iilicultyin this class of machines, to overcome which, I form acollar, f, whichfits closely to the shaft, and with a sleeve threaded so as to receiveover it a second collar, h, the lower collar f being itted to receivethelower edge of the upper cutters a, as seen in iig. 4.

The upper collar h is in like manner fitted to receive the upper edge ofthelower cutters d, as seen in iig. 3.

Therefore, by raising or lowering either of the two collars, h orf, thecutters supported thereby may be adjusted so that the lower edge of theupper set will overlap the upper edge of the lower set, as seen in flg.2

In the construction before described, for securing the cutters, it isnecessary that the cutters bev of an exact width, that is, the twocutters in each pair, for should one be a little wider than another, theupper head would bear upon the broader one first, and not be able toreach the second, or narrower.

To overcome this difficulty, I construct the upper head E concave uponthe upper side, as in figs. '3 and. 4, and bored out, so that while theupper side will Ht closely to the arbor, the lower side of the hole willper- This forms, as it were, a universal adjustment of theV cutters.

In working what are known-as waved mouldings, that is, a surface havinga corrugated form longitudinally, the materialY is moved by a pattern toand from the cutter, so as to produce the waved or corrugated surface.

To produce a'still greater variety of surface, I ar.- range a table, H,hinged or secured to the frame'at t, (or may be at the other en d,) so.that the unhinged end may be raisedand set to any desired degree ofelevation.

This-inclination, combinedwith the usual means of guiding the, materialso as to produce the waved or corrugated surface aforesaid, gives to themoulding au appearance of being carved, as the cutters indicate theincline on themoulding; and this, combined with the waving cut, throwsthe cutters out, and starts again immediately under the point at whichthecutters run .The combination-of the'two collars, fand it, with ltheir respective cutters, substantially in the manner IsAAc r. Tron.

herein set forth.
